Objectives: This study aimed to determine the frequency of epiretinal membrane (ERM) in the long term after neodymium-doped yttrium aluminum garnet laser iridotomy (LI) using spectral domain optical coherence tomography (SD-OCT).

Materials and methods: This retrospective study included 94 eyes that underwent LI for primary angle-closure glaucoma, were followed for at least 4 years, and had no ERM before the procedure. The control group consisted of 66 eyes that were followed for suspected glaucoma did not have a previous ERM. We compared the ERM frequencies of the groups at the last visit. Additionally, ERM frequencies were compared between those who had cataract surgery in the post-LI period and those who did not.

Results: After a follow-up period of at least 4 years, ERM developed in 36 of 94 eyes (38.2%) in the LI group. Of these, 32 were stage 1 ERM (34.0%) and 4 were stage 2 ERM (4.2%). In the control group, ERM developed in 13 of 66 eyes (19.6%), 12 of which were stage 1 ERM (18.1%) and 1 was stage 2 ERM (1.5%) (p=0.012). ERM developed in 14 of 32 eyes (43.7%) who underwent phacoemulsification surgery after LI and in 22 of 62 eyes (35.4%) that underwent only LI without subsequent cataract surgery (p=0.435). ERM developed significantly more frequently in the 62 phakic eyes that underwent only LI than in the eyes in the control group (p=0.045).

Conclusion: LI appears to be a predisposing factor for the development of ERM, regardless of subsequent cataract surgery.

In this study, we aimed to present a rare case of pulsatile proptosis due to sphenoid wing dysplasia without the features of neurofibromatosis type 1 (NF1). A 17-year-old male patient presented with swelling in the superotemporal region of the right eye. Physical examination revealed facial asymmetry with a pulsatile, ill-defined, soft lesion with in the superotemporal region of the right orbit associated with pulsatile proptosis, downward dystopia, and hypotropia. Computer tomography imaging to establish a differential diagnosis showed temporal lobe herniation secondary to sphenoid wing dysplasia. The patient was assessed for NF1, which is most commonly associated with sphenoid wing dysplasia, but no evidence supporting the diagnosis was found. Patients presenting with proptosis should be carefully examined for pulsation and murmurs, and a trauma history should be investigated. Radiological imaging should be used to facilitate the differential diagnosis, and the current clinical condition should be managed with a multidisciplinary approach.

Caffeine, commonly found in coffee and tea, affects various aspects of eye health as it blocks adenosine receptors, impacting tear production, intraocular pressure, macular perfusion, and choroidal thickness. However, its connection with eye conditions like glaucoma and cataracts remains uncertain due to conflicting research findings. Some studies suggest potential benefits for cataracts, while others warn against frequent caffeine intake in glaucoma and surgical scenarios due to possible increases in intraocular pressure. Conflicting evidence also exists regarding its effects on dry eye, macular degeneration, myopia/hyperopia, diabetic retinopathy, retinopathy of prematurity, and central serous retinopathy. Caffeine does not seem to be a risk factor for dry eye, although studies have shown that caffeine may offer protection against wet age-related macular degeneration, and the metabolite 7-methylxanthine could be a more promising treatment for myopia. Moreover, caffeine can potentially cause tremors and might hinder surgical performance, especially in less experienced surgeons. Recommendations from experts vary, highlighting the need for further research to fully understand how caffeine affects the eye. Individuals genetically predisposed to glaucoma should be cautious due to the possibility of clinically significant elevations in intraocular pressure with caffeine consumption. For delicate procedures like microsurgery, where tremors can be detrimental, caution should be exercised with caffeine. This review underscores the importance of additional studies to provide clearer insights and prudent recommendations regarding caffeine's impact on eye health.

Trabeculectomy is a primary surgical procedure used to reduce intraocular pressure (IOP) in patients with glaucoma. Despite its effectiveness, it can lead to significant complications, including hypotony, choroidal effusion, blebitis, and bleb leaks. Bleb leaks require prompt medical or surgical intervention to prevent severe complications such as blebitis and bleb-associated endophthalmitis. In recent years, the indications for collagen cross-linking (CCL) have expanded beyond corneal ectatic diseases to include various ocular conditions such as keratitis and leaking blebs. Here, we present the case of a 70-year-old male patient with a leaking avascular cystic bleb. Following treatment with a combination of conjunctival CCL, topical gentamicin, a dorzolamide/timolol combination, and a therapeutic contact lens, the patient experienced cessation of bleb leakage and an increase in IOP.

Objectives: Behçet uveitis (BU) is a potentially blinding disorder. The main determinant of visual prognosis is early and appropriate treatment that provides rapid suppression of inflammatory attacks, control of subclinical inflammation, and prevention of new attacks. Our study aimed to determine the Turkish uveitis specialists' approach regarding the treatment choices and management of special situations such as pregnancy, vaccination, and surgical planning in BU patients, and to increase information sharing and raise awareness of issues where knowledge is lacking.

Materials and methods: A web-based survey including 16 questions about the treatment approach in ocular involvement of Behçet's disease was sent via e-mail to uveitis specialists in Türkiye. Based on the answers of 49 ophthalmologists who responded to the survey, we evaluated the approaches of uveitis specialists in our country to initiating treatment, selecting therapeutic agents, monitoring, switching and stopping treatment, and special situations such as surgical planning, vaccination, and pregnancy in BU patients.

Results: Uveitis specialists in our country mostly act in accordance with the guidelines in the decision to start treatment, selection of therapeutic agents, and monitoring the safety of treatment in BU. However, there is a lack of information about the therapeutic approach in pregnancy and vaccination practices. It was also observed that there is no consensus on the precautions to be taken before cataract surgery.

Conclusion: Our study has shown that there is a need for more detailed and widespread information sharing on treatment in preparation for ocular surgery, safety monitoring, drug use during pregnancy, and vaccination in BU patients.

Objectives: To characterize the epidemiology of simultaneous traumatic brain injury (TBI) and ocular trauma.

Materials and methods: In this retrospective, observational study, de-identified data from patients admitted with ocular trauma and TBI was extracted from the National Trauma Data Bank (2008-2014) using International Classification of Diseases 9th Revision, Clinical Modification diagnostic codes and E-codes relating to injury circumstances. Mechanisms, types of ocular and head injuries, intention, and demographic distribution were determined. Association of variables was calculated with Student’s t and chi-squared tests and logistic regression analysis.

Results: Of 316,485 patients admitted with ocular trauma, 184,124 (58.2%) also had TBI. The mean (standard deviation [SD]) age was 41.8 (23) years. Most were males (69.8%). Race/ethnicity distribution was 68.5% white, 13.3% black, and 11.4% Hispanic patients. The mean (SD) Glasgow Coma Score (GCS) was 12.4 (4.4) and Injury Severity Score (ISS) was 17 (10.6). Frequent injuries were orbital fractures (49.3%) and eye/adnexa contusions (38.3%). Common mechanisms were falls (27.7%) and motor vehicle-occupant (22.6%). Firearm-related trauma (5.2%) had the greatest odds of very severe injury (ISS >24) (odds ratio [OR]: 4.29; p<0.001) and severe TBI (GCS <8) (OR: 5.38; p<0.001). Assault injuries were associated with the greatest odds of mild TBI (OR: 1.36; p<0.001) and self-inflicted injuries with severe TBI (OR: 8.06; p<0.001). Eye/adnexal contusions were most associated with mild TBI (OR: 1.25; p<0.001). Optic nerve/visual pathway injuries had greater odds of severe TBI (OR: 2.91; p<0.001) and mortality (OR: 2.27; p<0.001) than other injuries. Of associated head injuries, the odds of severe TBI were greatest with skull base fractures (OR: 4.07; p<0.001) and mortality with intracerebral hemorrhages (OR: 4.28; p<0.001). Mortality occurred in 5.9% of patients.

Conclusion: TBI occurred in nearly two-thirds of ocular trauma admissions. The mortality rate was low with implications for challenging rehabilitation and long-term disability in survivors.

Objectives: To evaluate the incidence and severity of depression in patients with retinitis pigmentosa (RP).

Materials and methods: The Beck Depression Inventory (BDI) was administered to 74 patients with RP and 60 healthy controls. Biomicroscopic anterior segment and fundus examination, visual field, optical coherence tomography, and full-field electroretinography tests were performed in all cases. Variables were evaluated with bivariate, multiple linear, and ordinal logistic regression analyses.

Results: The RP group included 40 (54%) male and 34 (46%) female patients, while the control group included 23 (38%) male and 37 (62%) female subjects. The patient group had a mean age of 39.20±12.4 years, median best corrected visual acuity (BCVA) of 0.10 decimal (1.0 logarithm of the minimum angle of resolution [logMAR]; range, 1.3-0.7 logMAR), and median visual field mean deviation (MD) score of -28.00 decibels (dB) (range, -1.00 to -34.00 dB). The median BDI score was statistically significantly higher in the patient group (19 points) than in the control group (12 points) (p<0.001). Moderate to severe depression (BDI ≥20) was detected in 61% of patients, while this rate was 25% in healthy controls. BCVA and visual field MD values were identified as predictors of depression score and severity level. The patients' age and gender did not affect total depression score or severity.

Conclusion: The prevalence and severity of depression were found to be higher in RP patients than in healthy controls. There was a significant relationship between the patient's functional vision tests and the frequency and severity of depression. Depression reduces the reliability of visual function tests and impairs patients' quality of life. Therefore, assessing mental health as well as functional tests is important in patients with RP.

Objectives: Computer vision syndrome (CVS) is a common disorder among children and is often associated with dry eye disease (DED). While researchers have shown a higher prevalence of psychopathology in older patients with DED, the impact of CVS-induced DED on the psychological state of children is not well known. This study aimed to evaluate psychological outcomes before and after DED treatment in pediatric patients with CVS-related DED.

Materials and methods: In this study, a total of 38 children (32 girls, 6 boys) with CVS-related DED were evaluated with the Schirmer test, tear break-up time (TBUT), ocular surface disease index (OSDI), and Oxford grading scale at the time of diagnosis and after treatment with artificial tear drops. Additionally, quality of life (QoL) and anxiety and depression symptoms were assessed using self-report scales for children.

Results: The mean age and mean daily screen exposure of the patients were 13.95±2.42 years and 5.65±2.31 hours, respectively. After treatment, TBUT and Schirmer test values of the patients increased significantly, while OSDI values decreased (p<0.001 for all). The anxiety and depression scores of the patients decreased, while QoL functionality scores increased (p<0.05 for all) following treatment. There were significant correlations between Schirmer test values and anxiety scores (r=-0.32, p=0.045) and QoL total scores (r=0.38, p=0.016).

Conclusion: Enhanced QoL and decreased anxiety and depression scores were associated with improved Schirmer test results, indicating that appropriate DED treatment may mitigate the psychosocial effects of CVS-related DED in pediatric patients.

Cystinosis is a rare autosomal recessive lysosomal storage disease associated with high mortality and morbidity rates. The most distinctive ocular manifestations of cystinosis are photophobia, tearing, and blurred vision. Herein, we assessed the ocular involvement of four patients from two families diagnosed with infantile nephropathic cystinosis using optical coherence tomography (OCT) and in vivo confocal microscopy (IVCM). Anterior segment OCT demonstrated multiple hyperreflective punctate deposits, and IVCM revealed needle-shaped bright crystal deposits in the corneal stroma in all patients. Three patients also had crystal deposits in the epithelium, where epithelial cell disruption was observed. Crystal deposits around the subepithelial nerve plexus were noted in some sections. In one patient, round and needle-shaped bright deposits along with inflammatory cells were observed in the limbal region of the conjunctiva. Infrared fundus images of two female siblings revealed hyperreflective crystal-like deposits around the optic disc, macula, and peripheral retina, and enhanced depth imaging OCT showed accumulation of crystals in all layers of the retina.
