Omnye wemisebenzi ephambili ye-gland ye-gland kukukwazi ukuthambisa amehlo, okhusela ekubeni ayome. Kwezinye iintlobo zezifo, amadlala amalahle ayayeka ukusebenza ngokufanelekileyo, onokubangela ukonakala kwamehlo. Oku kunokubonwa kwi-syndrome eyomileyo ye-shend, kodwa nezinye izifo ezonakalisa ngokusemandleni imisebenzi yeli phepha, ke izazinzulu zikhangela indlela esebenzayo yokubuyisela izigulana kunye nokudluliselwa kwizigulana.
UGqr Rachel Kalmann, i-Ophthalmologist yeZiko lezoLindo (i-UMC) e-Utrecht e-Itrecht eNetherlands wayengomnye wababhali bophononongo olutsha. Eli nqaku lineziphumo zomsebenzi wesayensi wapapashwa kwi-Comte yeseli yeseli. UGqr. Kalmann njengengxelo kwimpumelelo yakhe uqaphele oku kulandelayo:

Kwinqanaba lesibini, iingcali zenziwa luvavanyo lweesampulu zeeseli ze-pile yoluntu, ngokwenene zikhulisa ilungu elifanayo leeseli ze-microscopic.
Kwinqanaba lokugqibela, amadlala e-right ye-Dear ye-Proplocal yovavanyo olwenzekileyo ngokulungisa impumelelo.
