A 14-year-old male, presented to our clinic for a regular ophthalmic examination. Both Eyes Best Corrected Visual Acuity was 6/6, N6. The Indirect Ophthalmoscopic examination revealed an incidental finding in both eyes with patches of chorioretinal atrophy and pigment clumps along the veins consistent with pigmented paravenous chorioretinal atrophy (PPCRA) with early attenuation of retinal vessels, normal discs, and macula. ERG was normal. The patient was counseled and explained the nature of his condition. He was asked to be in yearly follow-up.

Each layer of the retina can be assessed using various electroretinographic techniques. A) A summary of the retinal origins of each response is shown here. B) Macular function can be assessed by pattern and multifocal ERG recording and provide a specific assessment of central vision, while flash tests are dominated by the more peripheral retina.

25-yr-old male presented to our retina clinic in 2007 with history of Hammer and chisel injury to left eye 2 months back. On examination BCVA in left eye was 20/20. Slit-lamp examination revealed iris hole and fundus examination showed an encapsulated metallic intraocular foreign body (IOFB) close to inferior arcade in left eye. Patient was advised Vitreous surgery with IOFB removal. Patient, however did not turn up for Surgery and revisited our clinic after seven years in 2014. On examination his BCVA was 20/20 in left eye and IOFB has reduced in size with brown siderotic deposits seen over IOFB capsule. Examination revealed posterior sub-capsular cataract but no siderotic changes with intraocular pressure (IOP) also being recorded as normal. In view of good visual acuity and no siderotic changes, he was advised regular follow up and ERG. Since most IOFBs would get timely removed by vitreous surgery, this Image capturing the natural course of a metallic IOFB is rare.

The patient is a 48 year old female who was noted to have an abnormal fundus on routine examination. Her past medical history is unremarkable. Her past family history is remarkable for her father being diagnosed with macular degeneration at age 72. Visual acuity was 20/20-1, J-2, OD and 20/20, J-1, OS. Amsler grid examinaton was normal, OU. All 6 of the AOHRR screening plates were identified correctly, OU. The 45 minute rod psychophysiologic threshold was normal, OU. ERG responses were normal for both rod and cone amplitudes. The cone implicit times were normal. The EOG was normal.
