FFA of these patients showed hyper-fluorescence in the macular area
. All patients were fully informed about the treatment and informed consent was obtained from each patient.
(12) Nd:YAG laser hyaloidotomy is another noninvasive method which enables drainage of extensive premacular subhyaloid hemorrhage into the vitreous, facilitates absorption of blood cells, and improves vision within days by clearance of the obstructed macular area
. (13) It has been advocated that hemorrhage less than 3 DD in size should not be subjected to photodisruptive laser for safety reasons.
The most frequently affected retinal structures or tissues seem to be those of the optic nerve head or papilla, the macular area
, and the choroidal vessels (as revealed by the attendant loss of pigment).
Calculations were also done for total volume of scanned macular area
. The macular thickness of these two groups was compared and Mann-Whitney U test (two tailed test, unpaired/independent) was used to calculate the differences between the two groups.
The loss of vision occurs when a thin layer of light sensing cells in the macular area
of the retina disappear.
We calculated the average RT using four corresponding sections in the inner and outer rings and ratio of the edematous areas in the macular area
. The number of pixels in highly swollen areas, indicated by the white area on OCT color maps, representing >500 [micro]m, was calculated using Adobe software (Photoshop CS6 Extended, Adobe Systems Inc., San Jose, CA) and divided by the pixels in the macular area
indicated by black lines in Figure 1(b).
Twenty eyes were treated with laser photocoagulation at peripheral retina, 2 at para macular area
and 10 at macula.
We found that decreased superficial and deep vascular density in macular area
were associated with longer AL, higher degree of myopia, and decreased GCC thickness.
On fundus examination, a well-defined round to oval area of shallow elevation of retina in the macular area
was noted with dull foveal reflex.
The macular area
of the right eye was slightly blurred compared to the other fundus features and appeared raised.
Observing a wider macular area
, namely, the central five fields (Figure 5), the mean retinal thickness in diabetics without DR showed increased thickness from the preoperative value of 284.2 to 291.2 [micro]m 6 months after surgery (p = 0.03) (Table 4).
Fundus fluorescein angiography (FFA) revealed nonperfusion in the macular area
with late staining of small veins and arterioles and leakage (Figures 3 and 4).
