Vortex Vein Decompression In Nanophthalmic Eyes

to show importance of doing vortex vein decompression surgery in nonophthalmic eyes in controlling IOP and reducing choroidal effusion which lead  to reduce the risk of complications that may occur during phaco surgery in nanophthalmic eyes

The Memorial Institute for Ophthalmic Research 

37 years old patient ,Bil. drop of vision
Examination showed that the patient had bilateral nanophthalmos
Bilateral axial lens 16.5 mm

Examination of both eyes:

Very faint cataract 

very high hyperopia+18.00

UCVA 1/60 , BCVA 6/60

Congested episcleral vessels

High IOP Rt 35    Lt 38  (wit out ttt)

On full antiglaucoma ttt Rt 20  and LT 25

Rt Crowded disc with  macular thickening

Lt cupping with C/D ratio 0.5 with macular thickening

Due to:

• very high IOP
• sever choroidal thickening
• very faint cataract

So, I decided to do vortex vein decompression  before cataract  to avoid complications during surgery and control IOP

steps of surgery ( shown in video)

6 months Post operative:

IOP 12 mmHg ( only 1 antiglaucoma)

VA 6/60 (the same)

Mild improvement in the choroidal thickening (2.63mm to 2.50 mm)

Marked improvement in the episcleral congestion (as shown in pic.)

After 6 months , we did the phaco in the original way 

vortex vein decompression surgery play an important role to prevent complications in nanophthalmic eyes
