Clinical profile and distribution of peripheral retinal changes in myopic population in a hospital-based study in North India

Purpose: To evaluate the prevalence of different types of peripheral retinal changes in a myopic population in North India and correlate them with axial length. Methods: This cross?sectional, hospital?based survey included 600 eyes of 300 myopic individuals, aged between 10 and 40 years, attending the outdoor ophthalmology clinic of a tertiary eye care hospital in North India were examined from July 2019 to July 2020. They were divided into mild, moderate, high, and severe myopia according to the spherical equivalent of refraction. Axial length was recorded. Peripheral retinal changes were examined by scleral indentation binocular indirect ophthalmoscopy. Standardized findings considered with their fundus location were lattice degeneration, white without pressure and white with pressure, snail?track degenerations, peripheral chorioretinal atrophy, retinal holes, tears, and detachment. The study was approved by the institutional ethics committee, and all participants provided informed consent. Results: Peripheral retinal degenerations were found in almost half (53%) of all myopes included in the study. The most common peripheral retinal degeneration found was lattice degeneration, followed by white without pressure, white with pressure, and chorioretinal atrophy. Most of the peripheral retinal degenerations were seen in the temporal quadrant of the fundus, either superotemporal or inferotemporal. There was a significant positive association between the prevalence of peripheral retinal degeneration with age, increased axial length, and severity of myopia. Conclusion: The results of our study indicate the necessity for careful peripheral fundus examinations of all myopes, irrespective of age and degree of myopia, for early diagnosis and better management of visual?threatening complications like retinal detachment.

A case of spontaneously resolved primary congenital glaucoma.

Primary congenital glaucoma usually presents as enlarged and hazy cornea at birth or early childhood. The diagnosis is based on a thorough clinical examination under anesthesia. Most cases require surgical intervention as the definitive treatment. In very rare instances, primary congenital glaucoma may arrest and resolve spontaneously. We describe a case of spontaneously arrested and resolved primary congenital glaucoma in a 37‑year‑old male presenting with large cornea, Haab’s striae, and normal intraocular pressure in one eye. Such a case has not been previously described from the Indian subcontinent.
