Global Ophthalmology: Making Impact as Retina Specialists


Nimesh Patel, MD Vitreo-retinal fellow Bascom Palmer Eye Institute This session was full of interesting presentations. Dr. Neiraj Jain started by sharing a series of 6 patients with a novel maculopathy associated with pentosan polysulfate sodium (PDS), a common treatment for cystitis. Notably, these were all cases that had a similar appearance to pattern dystrophy.

This study of ocriplasmin vs sham found that ellipsoid zone loss, external limiting membrane disruption or subretinal fluid at 24 months were poor prognostic signs.

These vesicles were able to be used to deliver labeled proteins to the retinal tissue in vivo. This could provide a future avenue for gene therapy delivery.

Peculiarly, 5 of the patients reported wearing ISO approved eyewear.

The mild cases stabilized, while the severe cases continually progressed and behaved more like retinal dystrophies. The reasons behind this phenomenon are still unknown, and these findings stress the importance of early detection.

The findings included saccular capillary telangiectasias as well as right angled vessels. Surprisingly, the findings resembled those seen in macular telangiectasia type 2 and could suggest a similar pathophysiology.

He shared some long standing cases of CSR that improved rapidly after treatment for the sleep apnea. Of interest, many of the patients had a normal body habitus.

The mean number of anti-VEGF injections that were given were 4.45. The treatment was was found to be efficacious.
