What is Tractional Retinal Detachment?
This occurs when scar tissue on the retina pulls it away from the underlying layer. It is often linked to diabetic retinopathy, where abnormal blood vessels form and create tension on the retina. Over time, this traction leads to distorted vision and progressive vision loss.
Symptoms of Tractional Retinal Detachment
-
Gradual diminution of vision
-
Visual field defect which usually progresses slowly
-
Mistari iliyonyooka (wadogo, ukingo wa ukuta, barabara, n.k.) ambayo ghafla huonekana ikiwa imejipinda
-
Central visual loss if macula is detached
-
Sudden drop in vision if associated with vitreous haemorrhage
Causes of Tractional Retinal Detachment
-
Proliferative retinopathy due to diabetes
-
Penetrating posterior segment trauma
-
Vaso-occlusive lesions leading to fibrovascular proliferation
-
Other causes such as retinopathy of prematurity, familial exudative vitreo retinopathy, idiopathic vasculitis
Prevention
-
Controlling the systemic parameters such as blood glucose levels and blood pressure
-
Kuchunguza macho mara kwa mara
-
Avoiding any trauma to the eyes
Types of Tractional Retinal Detachment
It can be classified based on type of vitreoretinal traction
-
Tangential- caused by the contraction of epiretinal fibrovascular membranes
-
Anteroposterior- due to the contraction of fibrovascular membranes extending from the posterior retina, usually in association with the major arcades, to the vitreous base anteriorly
-
Bridging(trampoline)- due to contraction of fibrovascular membranes stretching from one part of retina to another or between vascular arcades
Utambuzi

Tractional Retinal Detachment Treatment
- Katika kesi ya Tractional Retinal Detachment Treatment, juu ya utambuzi, uingiliaji wa upasuaji ni chaguo linalopendekezwa kwa madaktari karibu na matukio yote.
-
Retinal laser photocoagulation
-
Vitrectomy surgery
-
Intravitreal anti vegf injections (bevacizumab, ranibizumab, aflibercept)
Sometimes a tractional retinal detachment can be stopped before it affects the central vision. A small area of retinal detachment far from the center of the vision can sometimes be watched if it stops growing due to retinal laser or anit vegf injection treatment and improvement in blood sugars control. Other times, a tractional retinal detachment affects the central vision significantly enough to require surgical repair. The surgery performed is called a vitrectomy, or removal of the jelly in the back of the eye that the abnormal vessels are growing into. Vitrectomy is also combined with careful microscopic dissection of the fibrous scars left by the abnormal blood vessels from the surface of the retina. Laser is often performed simultaneously to reduce the risk of the vessels recurring or to treat stretch holes in the retina. To help keep the retina reattached, the eye is sometimes filled with a synthetic gas or silicone oil at the end of the repair. Oftentimes, the decision to use one of those materials as a vitreous substitute is made during the surgery.
Kwa kumalizia, ya Tractional Retinal Detachment Treatment na nyinginezo Matibabu ya Macho imeundwa kulingana na mahitaji ya mtu binafsi na ukali wa hali hiyo. Uingiliaji wa mapema, tathmini ya kina, na ushirikiano kati ya wataalamu wa huduma ya macho huchukua jukumu muhimu katika kuhakikisha matokeo ya mafanikio na utendakazi bora wa kuona.

Frequently Asked Questions (FAQs) about Tractional Retinal Detachment
Je, kizuizi cha retina kinaweza kusababisha upofu kamili?
Ndiyo, hata kuziba kidogo kwa maono kunakosababishwa na kutengana kwa sehemu ya retina kunaweza kusababisha upofu usipotibiwa mara moja.
Je, kuna dawa au matone ya jicho kwa ajili ya matibabu ya kikosi cha retina?
Hapana. Hakuna dawa, matone ya jicho, vitamini, mimea, au lishe ambayo ni ya manufaa kwa wagonjwa walio na kizuizi cha retina.
Je, jicho moja likipata mgawanyiko wa retina je lingine litaliendeleza pia?
Kutengana kuna uwezekano mkubwa wa kutokea ikiwa jicho lingine lina hali (kama vile kuzorota kwa kimiani) inayohusishwa na kutengana kwa retina kwenye jicho la kwanza. Ikiwa jicho moja tu linakabiliwa na jeraha kubwa au inahitaji upasuaji wa jicho basi, bila shaka, nafasi ya kujitenga katika jicho la pili haiongezeka kwa tukio hilo.
Je, upasuaji wa kutenganisha retina umefanikiwa kwa kiasi gani?
Mtazamo unategemea ukali wa hali hiyo na jinsi unavyopata haraka huduma ya matibabu ya kitaalam. Watu wengine watapona kabisa, haswa ikiwa macula haijaharibiwa. Macula ni sehemu ya jicho inayohusika na maono wazi na iko karibu na katikati ya retina. Walakini, watu wengine wanaweza wasipate tena maono kamili. Hii inaweza kutokea ikiwa macula imeharibiwa na matibabu hayatafutwa haraka vya kutosha.
