We report the choroidal findings on indocyanine green angiography (ICGA) in two cases of subacute sclerosing panencephalitis (SSPE). The two immunocompetent patients (31-year-old and 30-year-old Asian Indian males) presented with acute-onset rapidly progressing vision loss with findings of necrotizing retinitis involving the central macula. Both patients tested negative for serological evidence of herpes or varicella, and toxoplasma antibodies. The patients demonstrated high serum and cerebrospinal fluid titers of anti-measles antibody (and abnormal electroencephalogram in one patient) leading to the diagnosis of SSPE. ICGA of both patients revealed distinct "dark dots" which showed hypofluorescence in the early and late phases suggestive of choroidal involvement/hypoperfusion. Choroidal involvement in SSPE has not been evaluated before and must be considered in the pathological manifestations of the disease.

Objective: To evaluate the anatomical and functional macular results and rate of complications following surgical treatment of primary macular hole (MH) with autologous platelet rich plasma (a-PRP) use.

Design: retrospective, interventional, non-randomized case series.

Partecipants and methods: A cohort of 9 consecutive patients from January 1, 2019 to August 31, 2021 who underwent vitrectomy with a-PRP use for primary MH were included. Anatomical results based on spectral domain- optical coherence tomography (SD-OCT) and visual acuity were analyzed.

Results: 10 pseudophakic eye of 9 patients were enrolled. Six patients were female and three patients were male. The mean age was 69.9 years ± 1.48. The baseline MH minimum diameter was 486.1 μm ± 37.1, and mean pre operative best-corrected visual acuity (BCVA) was 0.91 ± 0.03 logMAR (Snellen equivalent 20/160). Mean 1 month post operative BCVA was 0.81 ± 0.57 logMAR (Snellen equivalent 20/130; p = 1.000); mean 3 month post operative BCVA was 0.66 ± 0.04 logMAR (Snellen equivalent 20/90; p = 0.006); mean 6 month post operative BCVA was 0.6 ± 0.04 logMAR (Snellen equivalent 20/80; p < 0.001). In all eyes, 10/10 (100%), there was a complete MH closure at 6 months follow up: 5 eyes (50%) with a U-type closure pattern, 4 eyes (40%) with a V-type pattern and 1 eye (10%) with an irregular foveal contour closure at 6 month follow-up. No ocular and systemic complications were reported.

Conclusion: The a-PRP use is a successful and promising vitreoretinal surgical technique option for primary MH.

Purpose: To analyze posttraumatic glaucoma regarding its demographics, presentations, different causes, surgical modalities, and hospitalization burden among patients in southern China.

Methods: This retrospective study investigated all individuals with posttraumatic glaucoma admitted to the Zhongshan Ophthalmic Center of Sun Yat-Sen University from January 2012 through December 2021.

Results: Out of 2211 cases, 64.82% had closed globe injury (CGI), 28.22% had open globe injury (OGI), and 6.96% had chemical injury (CI). The mean age of all patients was 44.45 ± 19.45 years old. Males (83.36%), rural patients (56.17%), and farmers (27.14%) predominantly had posttraumatic glaucoma. The most common external injury mechanism was blunt objects (37.82%). Compared with the other two groups, the majority of surgical modalities were cataract extraction (27.12%) in the CGI group, combined anterior-posterior surgery (34.79%) in the OGI group, and cyclocryotherapy/cyclophotoagulation (49.1%) in the CI group. The CI group had higher times of hospitalization (3.542 ± 0.242) and hospitalization duration (8.373 ± 0.743 days), whereas the OGI group had more operation expense ($ 1476.729 ± 11.047) and medical consumables expense per head ($ 962.578 ± 25.801).

Conclusion: Blunt injury, males, adults, farmers, and rural patients were high-risk factors for posttraumatic glaucoma. Chemical-induced glaucoma management requires a longer hospitalization period, while OGI requires more medical expenditure. This knowledge provides a new reference for clinicians to accurately diagnose and intervene in posttraumatic glaucoma. It also suggests that more education and long-term surveillance are needed regarding the presence of glaucoma after ocular trauma.

Purpose: To systematically analysis the burden and trends of blindness and vision loss for those aged ≥55 years from 1990 to 2019 and to predict trends over the next few years.

Methods: The data were extracted from the Global Burden of Disease Study (GBD) 2019. Trends from 1990 to 2019 were calculated using average annual percentage change (AAPC) by joinpoint regression analysis. Bayesian age-period-cohort (BAPC) models were used to predict future trends.

Results: In 2019, the global prevalence of blindness and vision loss was 471.1 million with 15.9 million disability-adjusted life-years (DALYs) for those aged ≥55 years. These numbers will reach 640.3 million cases and 18.9 million DALYs in 2030. The prevalence rate (per 100,000 population) increased from 32,137.8 (95% uncertainty interval [UI], 26,307.9-39,246.3) in 1990 to 33,509 (95% UI, 27,435.5-40,996.2) in 2019, with an AAPC of 0.143 (95% confidence interval [CI], 0.125-0.161; P < 0.001). The DALY rate (per 100,000 population) decreased from 632.9 (95% UI, 447.7-870.9) in 1990 to 579.3 (95% UI, 405.2-803.4) in 2019, with an AAPC of -0.293 (95% CI, -0.323-[-]0.263). Although the prevalence rates of cataracts, age-related macular degeneration, glaucoma, and near vision loss showed increasing trends from 1990 to 2019, the DALY rates indicated a downward trend for all blindness-causing diseases. The burden is heavier for women and in low Socio-demographic Index (SDI) regions.

Conclusions: Despite a decline from 2001 to 2019, the burden of blindness and vision loss, measured by prevalence and DALYs, continues to rise after adjusting for population growth and aging. Blindness and vision loss are significant public health burdens, especially for women and in low-SDI regions.

Background: Iridoschisis is a rare ophthalmological disorder that presents with the separation of the anterior fibers of the iris from the posterior ones at the level of the stromal layer. Fibers resulting from the disintegration of the anterior iris layers can be encountered in the anterior chamber of the affected eyes. This condition mostly affects females and has been associated with both open-angle and angle-closure glaucoma. The pathogenesis has not been clarified yet, and the treatment is still a matter of discussion.

Objective: We want to contribute to the understanding of the pathogenesis and natural course of the disease as well as to document with multimodal imaging a new case of this very rare disease.

Case report: We present a case of a 71-year-old woman affected by iridoschisis in both eyes followed by 3 consecutive visits every 4 months. We performed an extensive ophthalmologic examination, including gonioscopy, endothelial cell microscopy, and optical coherence tomography of the anterior segment.

Conclusion: In our report, we documented a possible natural course of iridoschisis, characterized by an acute worsening followed by a phase of stability, and formulated some hypotheses on the pathogenesis of this rare disease.

Introduction: Although monkeypox-related ophthalmic disease (MPXROD) is rare, visual impairing complications have been reported. At present, tecovirimat is the standard-of-care antiviral treatment. In this MPXROD case, the effect of tecovirimat was assessed with PCR analysis of tear samples and concurrent monitoring of inflammation with laser flare photometry (LFP).

Case description: The patient presented with a palpebral lesion and a corneal ulcer in his right eye, with complete absence of the corneal epithelium, high intraocular pressure and anterior uveitis. MPXV-DNA was detected in tear samples with real-time PCR (RT-PCR). A total volume of 0.5 ml tear-wash was aspirated from the inferior fornix, following instillation of saline onto the ocular surface. In addition, LFP was used to quantify inflammation in both eyes. Viral load in tear samples was detected prior to treatment initiation. In the left eye, tear samples tested negative for MPXV-DNA one week post-treatment while MPXV-DNA was still detected in the right eye, before reaching undetectable levels four weeks post-treatment. Objective quantification of anterior chamber inflammation through LFP demonstrated gradual decrease that was more pronounced in the affected right eye and coincided with the clinical improvement of the corneal ulcer.

Conclusions: This case of Mpox related corneal ulcer with associated uveitis manifests the feasibility of monitoring the antiviral effect of tecovirimat with virus detection in tear samples and LFP. Our observations indicate that tecovirimat resulted in viral load reduction in both eyes. RT-PCR MPXV detection in tear samples and LFP represent noninvasive tools that could assist with treatment response monitoring.

Purpose: To present the long-term outcome of the Cutler-Beard two-stage technique in patients with large full-thickness upper eyelid defects after tumor excision.

Methods: The medical records of 24 patients with large full-thickness upper eyelid defects reconstructed with the Cutler-Beard technique from January 2000 to January 2021 were retrospectively reviewed. All the defects involved ≥ 60% of the horizontal length of the upper eyelid and extended vertically for at least 15 mm from the eyelid margin. Patients with follow-up < 24 months were excluded. Long-term postoperative complications, functional outcome, and patient's satisfaction at the end of the follow-up were evaluated.

Results: Patients' age ranged from 36 to 88 (mean 66.0  ±  10.7 years) and 58.3% were females. Seven patients (29.2%) had had previous eyelid surgeries. The most common diagnosis was basal cell carcinoma (62.5%), followed by sebaceous gland carcinoma (12.5%), squamous cell carcinoma (8.3%), and Merkel cell carcinoma (8.3%). The mean duration of follow-up was 53.0  ±  16.9 months. Eleven patients (45.8%) developed upper eyelid entropion: 9 were treated conservatively with a therapeutic contact lens, 2 patients required a third operating stage. Most patients achieved a satisfactory functional and aesthetical outcome at the end of the follow-up.

Conclusions: Although non-bridging techniques are usually favored to reconstruct large upper eyelid defects, the Cutler-Beard bridge flap is a valuable technique in case of large horizontal defects where the vertical gap is greater than 15 mm. Further surgical steps are rarely necessary; however, alternative techniques should be considered following excision of highly malignant tumors.

Purpose: To compare the complication rates and surgical duration of cataract surgery using two 3D visualization systems and a traditional binocular microscope among experienced and inexperienced surgeons.

Methods: This retrospective case series included 571 eyes that received cataract surgery using either heads up cataract surgery, via a 3D head mounted system (N = 148-Group 1) or a 3D display screen (N = 338 eyes-Group 2), or traditional binocular microscope (N = 85 eyes-Group 3). The surgical records of consecutive patients who underwent cataract surgery by two groups of surgeons (experienced and inexperienced) were reviewed. Patients in all groups received either femtosecond laser assisted cataract surgery (FLACS) or traditional phacoemulsification. Complication rate, as well as duration of cataract surgery were evaluated between all three visualization approaches, between experienced and inexperienced surgeons.

Results: There was no statistically significant difference in duration of surgery between all 3 visualization approaches for both experienced and inexperienced surgeons (p < 0.05). Furthermore, the type of surgical technique (manual or FLACS) did not affect the surgical duration for both experienced and inexperienced surgeons (p < 0.05). No intraoperative complications were demonstrated in the current cohort.

Conclusions: The implementation of heads up-3D visualization either through a screen or a head mounted platform for cataract surgery seems to offer similar safety and efficiency as the traditional binocular microscope, and both experienced and inexperienced surgeons demonstrate the same outcomes in terms of safety and efficiency.

Purpose: To compare the safety and efficacy of micropulse laser (MP-TSCP) and slow coagulation transscleral cyclophotocoagulation (TSCP) with a diode laser for reducing intraocular pressure (IOP) in patients with refractory childhood glaucoma (CG).

Methods: Patients with CG and at least 12 months of medical chart data were included. Data on preoperative and postoperative outcomes were analyzed. The primary outcomes were an IOP of 6-21 mmHg and/or ≥ 20% reduction in the baseline value.

Results: A total of 17 eyes were included. The preoperative mean IOP was 28 mmHg in the MP-TSCP and 29.9 mmHg in the TSCP. The mean IOP decreased significantly to 17.26 ± 3.27 mmHg in the MP-TSCP and 14.68 ± 5.79 mmHg TSCP at the last medical record. Three anti-glaucoma meds were administered to the eyes preoperatively in both groups. A mean of 1.02 eye drops was administered to the MP-TSCP and 2.06 to the TSCP. The number of medications decreased by 2.38 ± 1.55 in the MP-TSCP and 0.82 ± 1.68 in the TSCP. The median preoperative visual acuity (logMAR) was 1.51 ± 1.06 in the MP-TSCP and 1.87 ± 0.74 in the TSCP. The variation in mean visual acuity (logMAR) was -0.027 ± 0.05 in the MP-TSCP and -0.40 ± 0.58 in the TSCP. The most frequent complication was corneal decompensation (one - MP-TSCP and two - TSCP).

Conclusion: Both techniques were effective and relatively safe for reducing IOP. These techniques appear to extend the indications of cyclophotocoagulation in CG eyes and improve the functional prognosis.

Purpose: To report the intermediate-term success rate of ultrasound cyclo plasty (UCP), predictors for failure and complications in advanced glaucoma.

Methods: This study included patients with advanced glaucoma who underwent UCP. The main outcome measures were intraocular pressure (IOP), the number of antiglaucoma medications, and the presence of complications. Success was defined as an IOP reduction ≥30% and IOP between 6 mmHg and 18 mmHg with no vision-threatening complications. Cox proportional hazard regression analysis was performed to identify possible predictors for failure.

Results: We included 65 eyes of 58 patients in the study. The mean IOP and number of antiglaucoma medications decreased significantly from 27.60 ± 5.5 mmHg and 3.40 ± 0.9 at baseline to 17.80 ± 8.0 mmHg (35.51% reduction) and 2.43 ± 1.3 at 12 months and 17.10 ± 8.2 mmHg (38.04% reduction) and 2.41 ± 1.5 at 24 months, respectively (p < 0.01 for both). The success rates were 66.2% (43/65) and 72.4% (21/29), while the failure rates were 33.8% (22/65) and 27.6% (8/29) at 12 and 24 months postoperatively, respectively. The cumulative probabilities of overall success were 67.7 ± 5.8% and 33.8 ± 5.9% at 12 and 24 months, respectively. High baseline IOP and history of old glaucoma surgery were associated with a higher risk for failure (Hazard ratio = 1.10 and 5.82, p = 0.03 and p < 0.01, respectively). The most common complications were anterior chamber reaction (18.5%) and cataract development/progression (15.4%). Two eyes (3.1%) developed phthisis bulbi.

Conclusions: Although UCP is effective in lowering IOP in eyes with advanced glaucoma, the intermediate-term success rates were moderate.
