With retinal whitening (Purtscher’s flecken) and intraretinal hemorrhages, Purtscher’s retinopathy was initially reported as a symptom of sudden loss of vision following head trauma in 1910. A 28-year-old male patient presented with a history of sudden painless decrease of vision in his left eye (LE) for 1 week. He gave a history of head-and-neck injury following a road traffic accident. Unaided distance visual acuity was 20/20 in the right eye (RE) and 20/40 in the LE which improved up to 20/25 on pinhole at the time of presentation. On examination, the anterior segment was within normal limits. Fundus photo and ocular coherence tomography (OCT) showed normal in the RE; however, LE showed multiple white patches around the optic disc with flamed-shaped hemorrhages on the fundus photo and macular edema with discontinuity in the inner and outer retinal layer on OCT. The patient received oral steroids as treatment, and after 1 month of follow-up, had recovered to 20/20 visual acuity.

Keratoconus (KC) is a bilateral sight threatening disease that affects the cornea. It consists of a gradual steepening of the central cornea associated with irregular astigmatism and may lead to corneal opacities. In some cases, a keratoplasty is needed to restore vision. Even though it is not frequent, recurrence of KC in donor tissue has been described, and is usually bilateral. Recurrence may respond to problems related to the corneal graft or to personal and environmental factors that persist after surgery. We present a case of a recurrent KC 20 years after a keratoplasty with clinical, topographic, and histopathological analysis.

We want to describe a case of inadvertent foveal burn during retinal laser in a patient with proliferative diabetic retinopathy (PDR). We report a 50-year-old male with PDR whose pattern scanning laser (Pascal®) procedure was complicated by an accidental foveal burn. On initial evaluation, the best-corrected visual acuity of the affected eye was 20/40. Fundoscopy revealed multiple laser burns in the macula, one of which crossed the fovea. The optical coherence tomography (OCT) showed an inadvertent burn at the foveal region and multiple parafoveal laser spots with the disrupted corresponding external limiting membrane (ELM), ellipsoid (EZ), and interdigitation zones. The patient underwent serial follow-up examinations. Six months after laser therapy, vision significantly recovered and improved to 20/20 in the affected eye. The results of follow-up OCT imaging showed that the ELM defect had fully recovered and the EZ defect had become smaller, as an unexpected and rare outcome. As a rare and interesting condition, laser burns around the foveal region seem to have the chance of retinal recovery over time. However, in most of the similar conditions, these accidental foveal laser burns lead to permanent severe visual impairment. Therefore, well-trained physicians must do retinal laser procedures.

A 36-year-old woman was scheduled for a vitrectomy of her left eye due to an epiretinal membrane (ERM) secondary to a retinal vasoproliferative tumor. Visual acuity (VA) was 20/20 in the right eye and 20/80 in the left. Before surgery, the patient’s vision had improved (20/20). Fundus examination and tomographic images revealed the spontaneous release of the ERM. ERM release usually presents after cryotherapy and photocoagulation. This is the first case in the literature documenting spontaneous ERM release in a vasoproliferarive tumor.

The purpose of this study was to describe the demographics and clinical profile of pigment dispersion syndrome (PDS) in patients presenting to a multi-tier ophthalmology hospital network in India. This cross-sectional hospital-based study included 2,961,706 new patients presenting between August 2010 and September 2021. Patients with a clinical diagnosis of PDS in at least one eye were included as cases. The data were collected using an electronic medical record system. Overall, 403 (0.014%) patients were diagnosed with PDS. Three fourth of the patients were male (75.43%) and 91.81% had bilateral affliction. The most common age group at presentation was during the fourth decade of life with 100 (24.81%) patients. In the 773 eyes, 443 (57.31%) eyes had mild or no visual impairment (<20/70) and blindness (>20/400) in 81 (10.48%) eyes. Krukenberg spindle was seen in 445 (57.57%) eyes and iris transillumination defects in 33 (4.27%) eyes. About a third of the eyes, 241 (31.18%) eyes had an intraocular pressure (IOP) >21 mm of Hg at presentation. Three hundred and twenty-eight (42.43%) eyes were on more than one anti-glaucoma medication. YAG peripheral iridotomy was documented in 100 (12.94%) eyes. In the 46 (5.95%) eyes that required a glaucoma related surgical intervention, combined surgery was performed in 30 (3.88%) eyes and trabeculectomy in 16 (2.07%) eyes. PDS is more common in males presenting during the fourth decade of life and is predominantly bilateral. A third of the eyes have raised IOP and a tenth of them are affected with blindness at presentation.

The objectives of this study were to report a case of phacolytic glaucoma with a lens-particle pseudohypopyon. This study was case report and literature review. A 66-year-old man with no comorbidities presented with gradual painless loss of vision in his left eye over 10 years. Ocular examination revealed visual acuity of 20/40 and light perception, for the right and left eye, respectively. The left eye slit-lamp examination disclosed extensive cornea guttae without edema or bullae, white fluffy material deposits on pupillary margin, poor mydriasis, hypermature cataract with intact lens capsule, and a mobile white cone-shaped deposit in the anterior chamber representing a lens-particle pseudohypopyon. Intraocular pressure was 32 mmHg. A B-scan ultrasonography was performed and showed increased anterior-posterior longitude due to posterior staphyloma and a large excavation of the optic nerve head. Corneal endothelial cell density was low, 880 cells/mm2. At this point, phacolytic glaucoma due to a hypermature cataract was diagnosed. Hypermature cataracts are commonly seen in developing countries and phacolytic glaucoma is a complication of a long-standing cataract.

The objectives of this study were to report the hospital-based incidence and a rare case series of Marcus Gunn jaw-winking phenomenon (MGJWP) in patients with congenital ptosis This was a retrospective non-interventional case series. The medical records of all patients diagnosed with MGJWP over the past 3.5 years were retrieved from the electronic medical record. Patients with documented evidence of the presence of ptosis with MGJWP were included and analyzed for visual acuity, the presence of squint and amblyopia, and the presence of other aberrant regenerations. A total of 198 patients were diagnosed with congenital ptosis, out of which 23 (11.6%) patients had MGJWP along with congenital ptosis and 175 (84.4%) patients have congenital ptosis without MGJWP. There were 12 males and 11 females. The mean age at presentation was 10.35 ± 8.4 years (range from 2 to 28 years). All the patients presented unilateral MGJWP. The right eye was involved in seven patients (30.4%) and the left eye in 16 patients (69.5%). Most of the patients had observed the onset of MGJWP by parents since birth. Visual acuity was measured by Snellen’s distance acuity chart in 15 patients. Eight patients were preverbal, and their vision was assessed by the fixation pattern, which was central, steady, and maintained. Nine patients (39.1%) were emmetropic, seven patients (30.4%) had astigmatism, and seven patients were amblyopic in the affected eye. Strabismus was noted in nine patients (39.1%) in this study. Monocular elevation deficiency was noted in five patients, three patients have exotropia, and one had hypotropia. All the patients had a mild form of MGJWP with no intervention required in any of the cases. The hospital-based incidence of MGJWP in congenital ptosis is 11.6%. Most of the patients had observed the onset of MGJWP by their parents since birth.

The choroidal vascularity index (CVI) is derived from the novel technique of assessing the choroidal vasculature by quantifying vascular flow using optical coherence tomography (OCT) images. Several retinal and choroidal diseases have been characterized using this index. However, no study has established the association of CVI with myopic traction maculopathy (MTM). This study aimed to investigate the association of CVI with different stages of surgically resolved MTM. We performed a consecutive, interventional, one-surgeon, and case-series study of 6 eyes of six patients enrolled between April 2017 and June 2022. One normal emmetropic eye (emmetropic control), one healthy myopic vision (healthy myopic control), and four surgically resolved myopic eyes at different stages of MTM (surgery group) were evaluated using OCT. The OCT images were binarized, and the total choroidal area (TCA, mm2), vascular luminal area (LA, mm2), and choroidal stromal area (SCA, mm2) were quantified using ImageJ software. The CVI (%) was calculated as the ratio of LA to TCA. The primary outcome measure was the association of the CVI with the best-corrected visual acuity in either of the study eyes. The baseline patient characteristics were similar (P > 0.05), except for visual acuity, which was better in the control eyes (P < 0.05). The CVI was 68.2% in the emmetropic control eye and 61.5% in the healthy myopic vision, whereas the mean CVI in the surgical group was 47.8% (40.9–53.3, min to max) (P = 0.07).

We report the case of a 50-year-old male who presented with a diminution of vision in his right eye for the past 6 months and was subsequently found to have central retinal vein occlusion with macular edema. The patient was given intravitreal triamcinolone in view of non-resolving macular edema despite repeated injections of anti-vascular endothelial growth factor. We report this rare occurrence of accidental injection of intravitreal triamcinolone acetonide in Berger space. A careful slit lamp examination before to look for the presence of prominent Berger space in patients planned for intravitreal injections, along with proper counseling of patients to avoid unwanted eye movements during an injection, can be potential ways to prevent such complications. In our case, the triamcinolone resolved after 6 weeks and the intraocular pressure (IOP) spike was managed using glaucoma medications. It is imperative to measure IOP at each visit in these patients and if spikes are noted, they should be managed accordingly.
