Purpose:
Description of evolving and resolving pattern of choroidal mounds at different quadrants post scleral buckle surgery in a myopic patient.
Methods:
A 48-year-old male with axial length of 32mm underwent scleral buckling for subtotal fresh retinal detachment with 360-degree multiple lattices with superior horse shoe tear. A posterior buckle was placed superiorly traversing 180-degree, 14 mm beyond muscle insertion. Uneventful drainage of sub-retinal fluid was performed intra-operatively.
Results:
Post-operative day 1 depicted two choroidal detachment (CD) mounds in the ST quadrant with an adequate break buckle relationship. Post-operative day 2 depicted an additional CD mound in the inferonasal with an additional mound supero-nasally on day 4. Spontaneous resolution of the mounds was observed from day 7 with complete resolution by one month.
Conclusion:
Fragility of the choroidal vasculature in axial myopia can aggravate venous congestion when associated with one or two vortex vein obstruction after scleral buckle. Choroidal vasculature remodeling occurs after vortex vein obstruction leading to formation of new venous drainage routes.
