# Gas tamponade followed by laser treatment for macular retinal detachment secondary to optic pit

## TL;DR

This study shows that injecting gas into the eye followed by laser treatment can help treat a type of retinal detachment caused by an optic pit.

## Contribution

The study introduces a new treatment approach combining gas injection and laser for optic pit-associated macular detachment.

## Key findings

- Five out of six patients showed complete fluid resolution without recurrence.
- One patient required an additional procedure for full recovery.
- Visual acuity improved in all patients after the treatment.

## Abstract

The study aimed to describe anatomic and visual outcomes associated with
perfluoropropane intravitreal injection followed by laser treatment for
macular retinal detachment secondary to optic disc pit.

A single-center, retrospective study. Medical records of all patients treated
at a tertiary retina referral center were evaluated between 2011 and 2018
for congenital optic disc pit-associated macular detachment with 0.3 ml 100%
perfluoropropane intravitreal injection followed by retinal laser
photocoagulation along the temporal optic disc margin as the initial
treatment.

Six patients with optic disc pit-associated macular detachment were
identified, with postoperative follow-up ranging from 13 to 52 months (mean:
28 months). Spectral domain optical coherence tomography (SD-OCT) showed
complete fluid resolution without recurrence in five of the six cases. Four
cases showed complete reabsorption after Intravitreal perfluoropropane plus
laser, one patient needed an extra procedure (pars plana vitrectomy with
inner limiting membrane peeling and pedicle flap inversion over the temporal
optic disc margin) to achieve complete fluid reabsorption, and one patient
had persistent intraretinal fluid and denied additional surgeries. The time
between the initial procedure and total fluid reabsorption varied from 6.5
to 41 months (mean: 19.5 months). Best-corrected visual acuity improved
after surgery on the last follow-up visit in all cases.

100% perfluoropropane intravitreal injection followed by photocoagulation
along temporal optic disc margin was associated with anatomic and visual
improvement in most cases, representing an alternative treatment approach
for optic disc pit-associated macular detachment.
